Schizosaccharomyces pombe (972h)

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.


Histone H2B mutations in inner region affect ubiquitination, centromere function, silencing and chromosome segregation.

The reiterated nature of histone genes has hampered genetic approach to dissect the role of histones in chromatin dynamics. We here report isolation of three temperature-sensitive (ts) Schizosaccharomyces pombe strains, containing amino-acid substitutions in the sole histone H2B gene (htb1+). The mutation sites reside in the highly conserved, non-helical residues of H2B, which are implicated in DNA-protein or protein-protein interactions ... [more]

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.
